Dumbest guy ever?

The joker I just saw on Cash Cab certainly is in the running. He was a 20something guy, so I'll cut him some slack for missing the second question. That said, he lasted about two blocks before he got booted. Missed the first three questions. Here they are:

1) What Olympics sport features a reverse two and a half somersault with a reverse half-twist pike?
His answer: Floor exercise
2) What screen queen became true royalty when she married Prince Rainer in 1956?
His answer: Audrey Hepburn.

3) What government agency does the initials FAA represent?
His answer: Federal Airline Agency.
